法兰科技名词定义中文名称：法兰英文名称：flange其他名称：凸缘定义：结构或机械零件上垂直于零件轴线突出的边缘。

所属学科：机械工程（一级学科）；机械零件（二级学科）；法兰（三级学科）本内容由全国科学技术名词审定委员会审定公布百科名片法兰盘法兰（Flange）又叫法兰盘或突缘。

法兰是使管子与管子相互连接的零件，连接于管端。

法兰上有孔眼，螺栓使两法兰紧连。

法兰间用衬垫密封。

法兰分螺纹连接（丝接）法兰和焊接法兰。

法兰是使管子与管子相互连接的零件，连接于管端。

法兰连接或法兰接头，是指由法兰、垫片及螺栓三者相互连接作为一组组合密封结构的可折连接，管道法兰系指管道装置中配管用的法兰，用在设备上系指设备的进出口法兰。

法兰上有孔眼，螺栓使两法兰紧连。

法兰间用衬垫密封。

法兰分螺纹连接（丝接）法兰和焊接法兰。

惟事美法兰编辑本段连接法兰连接(flange，joint)由一对法兰、一个垫片及若干个螺栓螺母组成。

垫片放在两法兰密封面之间，拧紧螺母后，垫片表面上的比压达到一定数值后产生变形，并填满密封面上凹凸不平处，使联接严密不漏。

法兰连接是一种可拆连接。

按所连接的部件可分为容器法兰及管法；按结构型式分，有整体法兰、活套法兰和螺纹法兰。

常见的整体法兰有平焊法兰及对焊法兰。

平焊法兰的刚性较差，适用于压力p≤4MPa的场合；对焊法兰又称高颈法兰，刚性较大，适用于压力温度较高的场合。

法兰密封面的型式有三种：平面型密封面，适用于压力不高、介质无毒的场合；凹凸密封面，适用于压力稍高的场合；榫槽密封面，适用于易燃、易爆、有毒介质及压力较高的场合。

对焊法兰垫片是一种能产生塑性变形、并具有一定强度的材料制成的圆环。

大多数垫片是从非金属板裁下来的，或由专业工厂按规定尺寸制作，其材料为石棉橡胶板、石棉板、聚乙烯板等；也有用薄金属板(白铁皮、不锈钢)将石棉等非金属材料包裹起来制成的金属包垫片；还有一种用薄钢带与石棉带一起绕制而成的缠绕式垫片。

法兰的基础知识一、法兰的基础知识法兰(flange)连接是管道施工的重要连接方式。

法兰连接就是把两个管道、管件或器材，先各自固定在一个法兰盘上，两个法兰盘之间，加上法兰垫，用螺栓紧固在一起，完成了连接。

有的管件和器材已经自带法兰盘，也是属于法兰连接。

法兰分螺纹连接（丝接）法兰和焊接法兰。

低压小直径有丝接法兰，高压和低压大直径都是使用焊接法兰，不同压力的法兰盘的厚度和连接螺栓直径和数量是不同的。

根据压力的不同等级，法兰垫也有不同材料，从低压石棉垫、高压石棉垫到金属垫都有。

法兰连接使用方便，能够承受较大的压力。

在工业管道中，法兰连接的使用十分广泛。

在家庭内，管道直径小，而且是低压，看不见法兰连接。

如果在一个锅炉房或者生产现场，到处都是法兰连接的管道和器材。

又叫法兰盘或突缘。

使管子与管子相互连接的零件。

连接于管端。

法兰上有孔眼，可穿螺栓，使两法兰紧连。

法兰间用衬垫密封。

法兰管件(flanged pipe fittings)指带有法兰(突缘或接盘)的管件。

它可由浇铸而成，也可由螺纹连接或焊接构成。

法兰联接(flange，joint)由一对法兰、一个垫片及若干个螺栓螺母组成。

垫片放在两法兰密封面之间，拧紧螺母后，垫片表面上的比压达到一定数值后产生变形，并填满密封面上凹凸不平处，使联接严密不漏。

法兰联接是一种可拆联接。

按所联接的部件可分为容器法兰及管法兰。

按结构型式分，有整体法兰、活套法兰和螺纹法兰。

常见的整体法兰有平焊法兰及对焊法兰。

平焊法兰的刚性较差，适用于压力p≤4MPa的场合；对焊法兰又称高颈法兰，刚性较大，适用于压力温度较高的场合。

法兰密封面的型式有三种：平面型密封面，适用于压力不高、介质无毒的场合；凹凸密封面，适用于压力稍高的场合；榫槽密封面，适用于易燃、易爆、有毒介质及压力较高的场合。

垫片是一种能产生塑性变形、并具有一定强度的材料制成的圆环。

大多数垫片是从非金属板裁下来的，或由专业工厂按规定尺寸制作，其材料为石棉橡胶板、石棉板、聚乙烯板等；也有用薄金属板(白铁皮、不锈钢)将石棉等非金属材料包裹起来制成的金属包垫片；还有一种用薄钢带与石棉带一起绕制而成的缠绕式垫片。
